APW7506 is a 1.5MHz high efficiency monolithic synchro-
nous buck regulator. Design with current mode scheme,
the APW7506 is stable with ceramic output capacitor. In-
put voltage from 3V to 5.5V makes the APW7506 ideally
suited for single Li-Ion battery powered applications. 100%
duty cycle provides low dropout operation, extending bat-
tery life in portable electrical devices. The internally fixed
1.5MHz operating frequency allows the using of small
surface mount inductors and capacitors. The synchro-
nous switches included inside increase the efficiency
and eliminate the need of an external Schottky diode.
The APW7506 is available in SOT-23-5/TSOT-23-5A
packages.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines Greento mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).

Note1: Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are
stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under "recom-
mended operating conditions" is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device
reliability.
